我出现的唯一错误是在那个类中找不到getName()和getSalary().我试图获取输入testEmployee类的信息以使用Employee并显示结果.我收到Build Successful消息但没有输出.

public abstract class Person {

    // Variables
    private String name;
    private String ssn = null;

    public Person(String name) {
        this.name = name;
    }

    // Pass data to the object Person
    /**
     * 
     * @param ssn
     */
    public void setSsn(String ssn) {
        this.ssn = ssn;
    }

    public String getSsn() {
        return ssn;
    }

    /**
     * 
     * @return
     */
    public abstract String getName();

}

class Employee extends Person {

    // Variables
    private String jobTitle;
    private double salary;
    private String getName; …
